In case there is any ambiguity of Mr. Jobs’ start date, CNBC and Reuters have him covered. They both report that he showed up for work Monday.

Jobs, who has been on medical leave since January, was seen by a Reuters reporter leaving the Apple campus in Cupertino, California dressed in his trademark black turtleneck and jeans. He walked out chatting with another person before climbing into a black car that then drove off.

There was no word on how many bathroom breaks he took nor what he had for lunch but we’ll follow up if that information becomes available.
